WARNING! Electric shock!
Opening the housing will expose
live parts!
ÎÎ Switch off power supply and disconnect the device from power
supply before opening the housing!
The unit must only be located in dry interior locations. It
is not suitable for installation in hazardous locations and
should not be placed close to any electromagnetic fields.The
controller must additionally be supplied from a double-pole
switch with contact gap of at least 0.12". Please pay atten­
tion to separate routing of sensor cables and mains cables.
1. Open the front cover by pushing it. Unscrew the crosshead screw from the cover and remove it along with the
front cover from the housing.
2. Mark the upper fastening point on the wall and drill and
fasten the enclosed wall plug and screw leaving the head
protruding.
3. Hang the housing from the upper fastening point and
mark the lower fastening point through the hole in the
terminal box (centres 5.3"). Drill and insert the lower
wall plug.
4. Hang the housing from the upper fastening point and
attach with the lower screw.
5. Carry out connection in accordance with the terminal
allocation.
6. Insert cover and attach with the cross-head screw. Close

Adjust the minimum runtime of the filter pump, in hours.
The pump will be switched on every day for this period of
time. This adjustment value is variable and has to be passed
through until the reference point (07:00 p.m.).
Example: When the filter runtime is adjusted to 5 hours,
the filter pump has to start at 02:00 p.m. and
continuously run until 07:00. p.m.
The minimum filter runtime will also be maintained in the
case of a sensor fault.

Expert/Options/Flow max.
If this function is activated, solar loading is stopped when
the maximum flow temperature has been exceeded. The
pool will be loaded again, if the flow temperature falls by
DT flowmax. below the maximum flow temperature.
The adjustable minimum difference between switch-on
temperature and switch-off temperture (hysteresis) avoids
that the controller switches on and off again at too low
temperature differences.

there is a temperature difference caused by high absorber
tem­peratures. “CS on” can be activated; the irradiation
threshold is adjustable (100-700 W/m²).
Heat quantitiy measurement is possible with the difference
between flow and return temperature, and with the flow
rate indicated by the flowmeter.
If “WMZ” is selected, flow temperature, return temperature,
flow rate and heat quantity will be displayed.
It is possible to use an additional WMZ module. Flow temperature, return temperature, flow rate and heat quantity
will also be displayed.

The function starts when the pool is being loaded. Solar loading means that pool loading is only carried out for energy
supply and not for cooling purposes etc.
Backup heating is suppressed when the temperature difference between flow and pool (AH solar on) is reached. If the
temperature difference falls below the value “AH solar off”,
the optimisation function switches off.

Circulation function
Expert/Options/Circulation
When the solar thermal system has been off for 1 hour, it
is switched on for 1 ... 10 minutes (the water of the swimming pool circulates through the pipes; this allows the pool
temperature to be detected during system standstill). If the
flow emergency shutdown is active, the circualtion function
is suppressed.

adjusted value (DT-Cool), heat is diverted, provided that
the absorber is by at least DTCool on colder than the
pool. Cooling is switched off when the value DTCool Off
is reached.
The adjustable minimum difference between switch-on
temperature and switch-off temperture (hysteresis) avoids
that the controller switches on and off again at too low
temperature differences.
When flowmeter is used and when the the filter pump is
switched on, this option monitors whether there is a flow
rate in the solar circuit. If the controller does not receive
any pulse after 2 minutes, the filter pump will be switchedoff and an error message will be generated.
This option is used for switching on an extra runtime of the
filter pump (in h) if necessary (e.g. in the case of polluted
pool water).
As soon as a contact is detected at the Din input, the filter
pump starts and remains switched-on for the adjusted period
of time (extra runtime).The filter minimum runtime will not
be influenced by this function.
The external release function is used for releasing the pump
for solar loading (e.g. for preventing the controller from
switching on the pump during pump maintenance.) The
Din input must be closed to deblock the controller (solar
loading, afterheating).
Adjust the sensor type for the solar irradiation sensor
(A to E).

An offset (-5K ... +5K, in 0.1 K steps) can be allocated to

Sensor fault
In the case of a sensor fault, an error message is generated:
Sensor defective.
! Sensor faulty
> Absorber
Signal relay (error message)
Expert/Options/Signal relay
Furthermore, the defective sensor will be recognised (absorber sensor, pool sensor or flow temperature sensor).
This function is switched on (option WMZ), when the
controller detects a fault. In this case, the signal relay is
energized (e.g. for signal lights).
These errors are:
! Sensor faulty
! Pump
!RTC
!EEPROM
• sensor defective
• pump defective
• real-time-clock (RTC) defective
• storage module (EEPROM) defective

Sensors
Our product range includes high-precision platin temperature sensors, flatscrew sensors, outdoor temperature
sensors, indoor temperature sensors, cylindrical clip-on
sensors and irradiation sensors, also as complete sensors
with immersion sleeve.
Overvoltage protection device
In order to avoid overvoltage damage at collector sensors
(e.g. caused by local lightning storms), we recommend installing the overvoltage protection RESOL SP10.
RESOL ServiceCenter Software
The software permits to read out measurement values of
the controller for visualising and controlling the system
status.

If you wish to carry out a heat quantity measurement,
you need a flowmeter for measuring the flow rate in your
system.
